Microsoft yesterday released an update for Windows 10 Build 9879 users. This december update KB3020114 fixes the Explorer crashing issues that few users were reporting since the build was released. While many of us were able to install it, some users experienced issues while installing it. Microsoft is working on a fix to solve this issue. You can also try some of the things described at Microsoft Community to install this update on your device.

While Microsoft has already confirmed that they are not going to release any Windows 10 Preview Build until end of this year, they are still sharing their updated builds with their partners. We recently reported about Windows 10 Build 9888 which includes updated animations and context menus, changes to Settings app and more. This build got leaked on the web and you can download it from file sharing sites.
